Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed. May 23, 1912. Serial No. 699,344.

To all whom it may concern- Be it known that I, lVALrnR D. NASH, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Universal Separators, of which the following is a specification.

This invention relates to separators and more particularly to separators adapted to separate the fine meats from the hulls 01 cotton seed.

The objects of the invention are to provide a machine for this purpose which is adapted to separate the meats from the hulls with a minimum amount of lint being removed from the hulls, requires a minimum amount of power to operate, is free from excessive vibration, is easily repaired and readily accessible for the purpose of repairing and cleaning.

The novel features of the invention will be apparent from the following description taken in connection with the accompanying drawings, in which,

Figure 1 is a side elevation of the machine; Fig. 2 is a longitudinal section thereof with certain parts shown in elevation; Fig. 3 is a plan view of the machine; Fig. 4 is an end elevation, and Fig. 5 is a transverse section on the line 5-5 of Fig. 2.

Referring to the drawings, 10 indicates a frame, of any suitable construction, on which is supported in bearings 11 and 12 a longitudinally extending shaft 13. The shaft 13 may be provided at one end thereof with a bevel gear 14 which meshes with a corresponding gear 15 on the driving shaft 16. The driving shaft 16 may be provided with a driving pulley 17 which may be driven by means of a belt from any suitable source of power. A pulley 18 may also be arranged on the shaft 16 for the purpose of driving a shaft 19, the latter being provided with a pulley 20, driven by means of a belt 21 passing over the pulley 18. The shaft 19 may be supported in suitable bearings 22, car ried by the frame of the machine. The shaft 13 may also be supported at the middle of the machine by means of a hanger 23 which may be secured to a cross piece 24 of the frame. A pair of cotiperating vibratory or shaking bins 25 and 26 may be suspended from the frame 10 by means of the rods 27, these rods being pivotally connected with suitable brackets 28 on the bins and also with pivot blocks 29 mounted on the frame. The rods 27 are preferably made adjustable in length as by having the ends thereof connected with the shank by right and left threads, the ends being secured to the shank by means of the lock-nuts 30. The bins 25 and 26 are preferably rectangular in form and have their bottoms formed of semi-cylindrical perforated plates 31 and 32, these plates being telescopically arranged, as clearly shown in Fig. 2. The plates 31 and 32 are secured to the sides of the bins 25 and 26 respectively by means of suitable straps 33. The bins may be provided with covers 34 which may be secured in position in any suitable manner, as by means of the bolts 35.

The shaft 19 is provided with two pairs of eccentrics 36 and 37, the eccentrics 36 being arranged in angular alinementv and the eccentrics 37 being also arranged in angular alinement and spaced angularly on the shaft 19, 180 from the eccentrics 36. The eccentrics 36 are connected with the eccentric rods 38, which are also connected with pivots on the brackets 39, which are secured to the bin 26. The eccentrics 37 have connected therewith the eccentric rods 40, the latter being also connected with pivots on brackets 41, secured to the bin 25. The bins 25 and 26 being freely suspended by means of the rods 27, it will be seen thatthe bins will be vibrated or shook by the eccentrics 36 and 37 when the shaft 19 is rotated. Owing to the fact that the eccentrics 36 are arranged at an angle of 180 to the eccentrics 37 the bins will be simultaneously moved in opposite directions and therefore the reaction due to the shaking of one bin neutralizes the reaction due to the shaking of the other and practically none of the vibrations are transmitted to the frame 10. By this arrangement all racking of the frame 10 is avoided and a very durable and efficient machine produced.

At one end of the bin 25 is arranged a feeding hopper 42 and the end of the bin adjacent the hopper is closed to prevent the material from falling out of the bin. At the opposite end of the machine from the hopper 42 the end of the bin 26 is open, as shown in Fig. 2, whereby the hulls may be discharged from the bins. In order to thoroughly separate the meats from the bulls and also move the material through the bins toward the discharge end of the bin 26 I have provided on the shaft 13 a series of beater arms or paddles 43 and 44, these arms being secured to the shaft in any suitable manner and provided with broad flat ends which are adapted to separate the meats from the hulls with the least amount of lint being beaten from the hulls into the meats. The arms 43 are preferably ar ranged at an angle to the axis of the shaft 13, as clearly shown in the drawings, whereby they are adapted to move the material longitudinally of the bins toward the discharge end as the shaft 13 is rotated. The arms 44 are preferably straight and substantially in alinement with the axis of the shaft 13 and therefore have no tendency to move the material longitudinally of the bins. In arranging the arms 43 and 44 on the shaft 13 I prefer to alternate each pair of the arms 44 with two pairs of the arms 43, as clearly shown in Fig. 2.

Arranged below the bins 25 and 26 is a conveyer-box 45, in which is arranged any suitable form of conveyer, such as the helicoidal conveyer 46, which may be driven by means of a sprocket 47. A sprocket 48 may be arranged on the shaft 13 and drive the sprocket 47 by means of a chain 49. The conveyer-box may be of ordinary construction and provided with an outlet 50 at any desired point.

The frame 10 may be provided with the removable side panels 51 and below the bins 25 and 26 may be arranged removable cant boards 52 which receive the meats which pass through the perforated bottoms of the bins and deliver these meats to the conveyer-box 45.

In order to close the space between the side edges of the covers 34 and the frame 10, suitable strips 53 may be secured along the top of the frame.

In the operation of the machine the rotation of the shaft 13 causes the beater arms or panels 43 and 44 to separate the meats from the hulls and the vibratory or shaking movement of the bins tends to aid in passing the meats through the perforated bottoms of the bins and thereby keep the perforations clear. The combined action of the beater arms or paddles and the shaking bins renders the machine especially adapted to handle wet material. By having the side panels 51 and the cant boards 52 readily removable, it will be seen that the interior of the machine is perfectly accessible for purposes of cleaning or repair.

The bin 26 may discharge the hulls into a compartment 54, whence they may be dis charged into any suitable conveyer or chute. In order to permit access to the interior of thecompartment 54, a gate 55 may be provided.
